The seat which may be adjustable in height by a lazy-tongs arrangement 12 may be supported on the vehicle by three pivoted links (9), Fig. 5 (not shown) 10, 11 disposed one at the front and two at the rear of the seat. Alternatively, the seat may be movably supported on a spherical member 4 or on two pairs of curved rails at right angles to each other. The springs which may comprise four rubber bands disposed at right angles to each other may be of adjustable tension to compensate for persons of different weights. The seat may be held in position relative to the vehicle by an electric hydraulic or mechanical brake 19.
